Peter Jones has been a dragon on Dragons' Den since the British programme began.
Jones joined the original panel when the BBC series launched in 2005 and became its longest-serving investor. He is a British entrepreneur and businessman whose interests have included technology, media, retail, and leisure businesses.
On the programme, Jones is known for examining a company's financial figures, market potential, and the entrepreneur's proposed valuation. As with every dragon, an on-screen offer is subject to negotiation and may not ultimately become a completed investment.
Several other prominent dragons appeared in the early series, including Duncan Bannatyne, Theo Paphitis, Deborah Meaden, and Rachel Elnaugh. Their tenures were not identical, which is why Jones is the specific answer to the programme-long service question.
